WATER-GAG E.

SPECIFICATION forming part of Letters Patent No. 721,763, dated March 3, 1903.

Application filed June 11,1902.

To all whom, 25 may concern:

Be it known that we, CLEMENs WERNER,

CARL MALTNER, and FRITZ BANSEN, subjects Figure l shows a cross-section of the headA of a Water-gage, the metal ball being shown in its automatically-closed position after the breaking of the glass. `lig. 2 shows a portion of Fig. l, but with the ball closing the communication with the generator by positive means.

The gage-head is fitted with a screw-spindle A, having a high pitch, and a cup-shaped inner end a, located in a chamber b, spherical or cup-shaped 'at its opposite portion, asV indicated in the figures. The cup-shaped end of the said spindle and the spherical or cup-shaped portion of the chamber b are arranged opposite each other and normally allow free play to a ball of metal and of a diameter larger than the inlet passage b'.

, When the spindle, with its cup-shaped end a,

cl. So soon as the glass breaks the boilerpressure will at once force the ball against the orice c, and thereby prevent any further egress of Water-or steam to the broken gageglass. (See Fig. l.) When the inlet-passage from the steam-generator is to be closed, the screw-spindle A 'is screwed inward, and in this manner the cup-shaped end a catches the ball and forces it rearward into the oupshaped end of the chamber b, as shown in Fig. 2, and by thus pressing the ball tightly against thev oriiioe b' of said chamber an absolutely tightk joint is insured even for very high steam-pressures.

Having now fully described our said invention, what we claim,` and desire to secure by Letters Patent, is-

A water-gage provided with a casing having an inlet from the boiler and an outlet to the gage-glass, a ball in the casing automatically closing the outlet when the gage-glass breaks, and a spindle extending into the casing having a cup-shaped head thereon adapted to engage the ball and force the same to the inlet.

In testimony whereof We have hereunto set our hands in presence of Witnesses.
